Product Advantage
It boasts excellent pearlescent performance. When dissolved or emulsified in surfactant complexes by heating and crystallized during cooling, it forms mirror-like flakes, creating a more delicate pearlescent luster than ethylene glycol bis-stearate. With a melting point of 55-60°C and a flash point of 240°C, it ensures stable performance in various processing conditions.
It has strong compatibility and stability. Compatible with most surfactants, it maintains stability over a wide pH range. Its acid value is ≤5mgKOH/g and saponification value ranges from 170-190mgKOH/g, meeting strict quality standards and ensuring reliable use in different formulations.
It offers multiple functional benefits. Besides being a pearlescent agent, it acts as a thickener, emulsifier, and viscosity regulator, increasing product viscosity. It also has moisturizing, hair-nourishing, and anti-static properties, adding extra value to end products without irritating the skin or damaging hair.
It features versatile application methods. Suitable for both hot and cold mixing processes; for cold mixing, it just needs to be pre-prepared into pearlescent paste. With a density of 0.913g/cm³, it is easy to handle and integrate into various production systems, improving manufacturing efficiency.
It comes with reliable quality assurance. Produced through a precise esterification process (using 0.95mol stearic acid, 1mol glycol, etc.) and strict quality control, it has a 24-month shelf life. Packaged in 20/25KG bags or plastic drums, it ensures safe storage and transportation.

Product Uses
In Personal Care Products: Widely used in shampoos, bath gels, and hair conditioners. It adds a soft, rich pearlescent glow, thickens products, regulates viscosity, and provides moisturizing and anti-static effects, enhancing the sensory experience and quality of these daily care items.
In Cosmetics: Acts as a suspending agent for insoluble small particles in skin creams, lotions, and lipsticks. It improves product texture, ensures even distribution of ingredients, and maintains stability, making cosmetics more appealing and effective.
In Cleaning Products: Applied in high-end liquid detergents and dishwashing liquids. It creates a noticeable pearlescent appearance, increases product viscosity for better usability, and enhances cleaning performance while being gentle on hands, elevating product market competitiveness.
In Pharmaceutical Industry: Serves as a pearlescent dispersant, solubilizer, and lubricant in pharmaceutical production. It helps in the uniform dispersion of active pharmaceutical ingredients, improves drug solubility, and facilitates the manufacturing process of various pharmaceutical formulations.
In Industrial Auxiliaries: Used as a metalworking washing agent, plastic auxiliary, and textile auxiliary. It provides lubrication and cleaning functions in metal processing, improves plastic processing properties, and enhances textile softness and anti-static performance, meeting industrial production needs.
1、Pre-treatment: Melt EGMS at 55-60°C (its melting point) for uniform mixing; avoid overheating above 240°C (flash point).
2、Adding: For hot mixing, add melted EGMS directly to formulations; for cold mixing, pre-make it into pearlescent paste first.
3、Post-addition: Stir gently to ensure dispersion; maintain pH stability (compatible with most pH ranges) for optimal performance.
